From the developer:
Opusmodus is an application designed for music composition. At the heart of Opusmodus is the Composer panel. This is where the script for a new piece of music comes together. It starts as a blank page, but composers quickly learn to fill it with expressions that can be seen as a score, auditioned, shown as notation or visualized graphically.
